Subject: [PATCH] Don't split by default

References: bsc#1036223, bsc#1068234
Patch-mainline: v0.8.17
Git-commit: 51a68c31497d1895602d5c6851e23a9027d9675d

Currently, we are default'ing to "SPILT" as well as multi-threading
when KDUMPTOOL_FLAGS="". Ensure split is enabled only when it is set
explicitly with KDUMPTOOL_FLAGS="SPLIT".
